ROLLINGWINDOVV-SGBEEN-ATTACHING DEVICE.

Specification of Letters Patent.

Patented Nov. "2, 1916.

Application filed May 25, 1914. Serial No. 840,683.

To all whom it may concern:

Be it known that I, MORTON G. BUNNELL, citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Rolling- Window- Screen-Attaching Devices, of which the fol lowing is a specification.

My invention relates to rolling screens of the kind in which means are provided for attaching one edge of the screen to the window sash, either the upper or the lower sash, and in which the opening of the window, by raising or lowering one of the sashes, serves automatically to bring the screen into position.

The object of my invention is to provide novel and effective means for detachably connecting the screen with the sash.

To this and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings :Figure 1 is an inside elevation of the lower portion of an ordinary guillotine sash window, showing the lower sash raised, and showing the same equipped with a rolling screen attaching means embodying the principles of my invention. Fig. 2 is a vertical section of the lower portion of the window, on a larger scale, showing the sash only partially raised.

As thus illustrated, the window frame A and sash B may be of any suitable formor construction. The roll C for the flexible screen D is disposed in any suitable manner in the frame below the sill and in the plane of the sash. A slot a in the frame permits the screen to move up and down with the sash. It will be understood that said roll has a suitable spring for automatically winding or rolling up the screen when the sash is lowered.

A metal strip E is secured to the lower end of the sash B, in any suitable manner, the upper edge of said strip being bent over toward the window glass to form a curved flange c which overhangs the sash. The screen D has the upper edge thereof soldered or brazed or otherwise secured to the inner surface of the similar strip F, which latter has a curved flange f at its upper edge.

l Vhen in place the flange f rests on the flange 6, and the pull of the screen keeps this hooklike element in place. Handles f are secured to the strip F, and by pulling upward on these handles the flange f is raised fromthe flange e, or unhooked, so to speak, and the sash can then be raised and lowered without the screen. When detached the strip F rests on the window frame below the sash. Thus, and with the simple attaching device, the screen can be instantly and readily detached when not needed, or when it is desired-to wash the window, or for any other reason.

I do not limit myself to the exact construction shown and described.

l/Vhat I claim as my invention is 1. A rolling window screen provided with 7 a roll disposed in the plane of the sash, below the lower edge of the latter, and having a sheet metal strip secured to the upper portion thereof, the edge of said strip being turned over to form a hooking flange, and means for engaging the hook thus provided on the screen, carried on the window sash, said flange and means being separable to permit disconnection of the screen from the sash.

2. A rolling window screen having a sheet metal strip secured to the upper portion thereof, the edge of said strip being turned over to form a hooking flange, and means for engaging the hook thus provided on the screen, carried on the window sash, said flange and means being separable to permit disconnection of the screen fromthe sash, said means comprising a sheet metal strip with its upper edge turned over to form a curved portion similar to said flange, the screen being secured to the inner surface of the first mentioned strip and in the plane of the body portion of said other strip.

3. A rolling window screen provided with a roll disposed in the plane of the sash, below the lower edge of the latter, and having a sheet metal strip secured to the upper portion thereof, the edge of said strip being turned over to form a hooking flange, and means for engaging the hook thus provided on the screen, carried on the window sash, said flange and means being separable to permit disconnection of the screen from the sash, said means including a strip of sheet Signed by me at Chicago, Illinois, this metal secured to the sash, disposed with the 29th day of April, 1914. lower edge thereof ad] acent the upper edge MORTON G.
